This code uses Bootstrap's CDN (Content Delivery Network) to load the necessary CSS and JavaScript files. The page includes a responsive navigation bar with three links, as well as a header section with an image and text. The layout is managed using the Bootstrap grid, with two columns for the header. The page is also made responsive by using Bootstrap classes such as "img-fluid" for the image and "mt-5" for the top padding.
